I should add that both this Mark 3 and my Veloster do the exact same thing...
If I shut off the car I will hear what sounds like a motor and clicking in the Focus and in the Veloster I will just hear clicking because said Veloster has no active grille shutters.
The clicking from what I've can tell is the transmission resetting itself for the next startup or something to that affect. Nothing severe or dangerous at all.
Same with opening up the doors or a 'pre-start', your tranny is getting ready to go.
Try it, don't start the car just go into ACC/Power mode and you'll hear more clicking and I'd bet several pesos that all the clicking is coming from the transmission.
